UV weathering test chamber how to make the correct choice of light source and spray control

UV weathering tester is widely used for non-metallic materials, organic materials (such as: coatings, paints, rubber, plastics and their products) by the sun, humidity, temperature, condensation and other changes in climate conditions to test the degree of aging phenomenon of products and materials, in a short period of time to get discoloration, fading and other situations.Ah2Textile Testing Instruments, Testing Equipment Manufacturer

6, because the fluorescent lamp light energy output will gradually decay over time, in order to reduce the impact of the test due to light energy decay, so the test chamber in all 8 lamps every 1/4 of the fluorescent lamp life, by a new lamp to replace an old lamp, so that the UV light source is always composed of new and old lamps, so as to get a constant output of light energy;Ah2Textile Testing Instruments, Testing Equipment Manufacturer

2, spraying state monitoring: the machine is equipped with a spraying device, spraying device simulates the temperature change and rain erosion when it rains, there are a number of nozzles, spraying evenly. When to spray, spraying how long, are set by the customer freely.Ah2Textile Testing Instruments, Testing Equipment Manufacturer
